TFRS Tutorial Ported to TFX

This is a port of a basic TensorFlow Recommenders (TFRS) tutorial to TFX, which is designed to demonstrate how to use TFRS in a TFX pipeline. It mirrors the basic tutorial.

For context, real-world recommender systems are often composed of two stages:

  1. The retrieval stage is responsible for selecting an initial set of hundreds of candidates from all possible candidates. The main objective of this model is to efficiently weed out all candidates that the user is not interested in. Because the retrieval model may be dealing with millions of candidates, it has to be computationally efficient.
  2. The ranking stage takes the outputs of the retrieval model and fine-tunes them to select the best possible handful of recommendations. Its task is to narrow down the set of items the user may be interested in to a shortlist of likely candidates.

In this tutorial, we're going to focus on the first stage, retrieval. Retrieval models are often composed of two sub-models:

  1. A query model computing the query representation (normally a fixed-dimensionality embedding vector) using query features.
  2. A candidate model computing the candidate representation (an equally-sized vector) using the candidate features

The outputs of the two models are then multiplied together to give a query-candidate affinity score, with higher scores expressing a better match between the candidate and the query.

In this tutorial, we're going to build and train such a two-tower model using the Movielens dataset.

We're going to:

  1. Ingest and inspect the MovieLens dataset.
  2. Implement a retrieval model.
  3. Train and export the model.
  4. Make predictions

The dataset

The Movielens dataset is a classic dataset from the GroupLens research group at the University of Minnesota. It contains a set of ratings given to movies by a set of users, and is a workhorse of recommender system research.

The data can be treated in two ways:

  1. It can be interpreted as expressesing which movies the users watched (and rated), and which they did not. This is a form of implicit feedback, where users' watches tell us which things they prefer to see and which they'd rather not see.
  2. It can also be seen as expressesing how much the users liked the movies they did watch. This is a form of explicit feedback: given that a user watched a movie, we can tell roughly how much they liked by looking at the rating they have given.

In this tutorial, we are focusing on a retrieval system: a model that predicts a set of movies from the catalogue that the user is likely to watch. Often, implicit data is more useful here, and so we are going to treat Movielens as an implicit system. This means that every movie a user watched is a positive example, and every movie they have not seen is an implicit negative example.

Imports

Let's first get our imports out of the way.

pip install -Uq tfx
pip install -Uq tensorflow-recommenders
pip install -Uq tensorflow-datasets

Uninstall shapely

TODO(b/263441833) This is a temporal solution to avoid an ImportError. Ultimately, it should be handled by supporting a recent version of Bigquery, instead of uninstalling other extra dependencies.

pip uninstall shapely -y

Did you restart the runtime?

If you are using Google Colab, the first time that you run the cell above, you must restart the runtime (Runtime > Restart runtime ...). This is because of the way that Colab loads packages.

Create a TFDS ExampleGen

We create a custom ExampleGen component which we use to load a TensorFlow Datasets (TFDS) dataset. This uses a custom executor in a FileBasedExampleGen.

Create inspect_examples utility

We create a convenience utility to inspect datasets of TF.Examples. The ratings dataset returns a dictionary of movie id, user id, the assigned rating, timestamp, movie information, and user information:

def inspect_examples(component,
                     channel_name='examples',
                     split_name='train',
                     num_examples=1):
  # Get the URI of the output artifact, which is a directory
  full_split_name = 'Split-{}'.format(split_name)
  print('channel_name: {}, split_name: {} (\"{}\"), num_examples: {}\n'.format(
      channel_name, split_name, full_split_name, num_examples))
  train_uri = os.path.join(
      component.outputs[channel_name].get()[0].uri, full_split_name)

  # Get the list of files in this directory (all compressed TFRecord files)
  tfrecord_filenames = [os.path.join(train_uri, name)
                        for name in os.listdir(train_uri)]

  # Create a `TFRecordDataset` to read these files
  dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")

  # Iterate over the records and print them
  for tfrecord in dataset.take(num_examples):
    serialized_example = tfrecord.numpy()
    example = tf.train.Example()
    example.ParseFromString(serialized_example)
    pp.pprint(example)

      }
    }
  }
  feature {
    key: "user_gender"
    value {
      int64_list {
        value: 1
      }
    }
  }
  feature {
    key: "user_id"

    }
  }
  feature {

    value {
      bytes_list {
        value: "53211"
      }
    }
  }
}

The movies dataset contains the movie id, movie title, and data on what genres it belongs to. Note that the genres are encoded with integer labels.

inspect_examples(movies_example_gen)
channel_name: examples, split_name: train ("Split-train"), num_examples: 1

features {
  feature {
    key: "movie_genres"
    value {

    }
  }
  feature {

    value {
      bytes_list {
        value: "1681"
      }
    }
  }
  feature {
    key: "movie_title"
    value {
      bytes_list {
        value: "You So Crazy (1994)"
      }
    }
  }
}

ExampleGen did the split

When we ingested the movie lens dataset, our ExampleGen component split the data into train and eval splits. They are actually named Split-train and Split-eval. By default the split is 66% training, 34% evaluation.

Generate statistics for movies and ratings

For a TFX pipeline we need to generate statistics for the dataset. We do that by using a StatisticsGen component. These will be used by the SchemaGen component below when we generate a schema for our dataset. This is good practice anyway, because it's important to examine and analyze your data on an ongoing basis. Since we have two datasets we will create two StatisticsGen components.

movies_stats_gen = tfx.components.StatisticsGen(
    examples=movies_example_gen.outputs['examples'])

Create schemas for movies and ratings

For a TFX pipeline we need to generate a data schema from our dataset. We do that by using a SchemaGen component. This will be used by the Transform component below to do our feature engineering in a way that is highly scalable to large datasets, and avoids training/serving skew. Since we have two datasets we will create two SchemaGen components.

Feature Engineering using Transform

For a structured and repeatable design of a TFX pipeline we will need a scalable approach to feature engineering. This allows us to handle the large datasets which are usually part of many recommender systems, and it also avoids training/serving skew. We will do that using the Transform component.

The Transform component uses a module file to supply user code for the feature engineering what we want to do, so our first step is to create that module file. Since we have two datasets, we will create two of these module files and two Transform components.

One of the things that our recommender needs is vocabularies for the user_id and movie_title fields. In the basic_retrieval tutorial those are created with inline Numpy, but here we will use Transform.

Implementing a model in TFX

In the basic_retrieval tutorial the model was created inline in the Python runtime. In a TFX pipeline, the model, metric, and loss are defined and trained in the module file for a pipeline component called Trainer. This makes the model, metric, and loss part of a repeatable process which can be automated and monitored.

TensorFlow Recommenders model architecture

We are going to build a two-tower retrieval model. The concept of two-tower means we will have a query tower computing the user representation using user features, and another item tower computing the movie representation using the movie features. We can build each tower separately (in the _build_user_model() and _build_movie_model() methods below) and then combine them in the final model (as in the MobieLensModel class). MovieLensModel is a subclass of tfrs.Model base class, which streamlines building models: all we need to do is to set up the components in the __init__ method, and implement the compute_loss method, taking in the raw features and returning a loss value.

# We're now going to create the module file for Trainer, which will include the
# code above with some modifications for TFX.

Exporting the model

After training the model, we can use the Pusher component to export the model.

_serving_model_dir = os.path.join(tempfile.mkdtemp(), 'serving_model/tfrs_retrieval')

pusher = tfx.components.Pusher(
    model=trainer.outputs['model'],
    push_destination=tfx.proto.PushDestination(
        filesystem=tfx.proto.PushDestination.Filesystem(
            base_directory=_serving_model_dir)))
context.run(pusher, enable_cache=True)

Make predictions

Now that we have a model, we load it back and make predictions.

loaded = tf.saved_model.load(pusher.outputs['pushed_model'].get()[0].uri)
scores, titles = loaded(["42"])

print(f"Recommendations: {titles[0][:3]}")
Recommendations: [[b'Substance of Fire, The (1996)' b'8 1/2 (1963)'
  b'Object of My Affection, The (1998)' b'Made in America (1993)'
